FIELD

The present disclosure relates, generally, to a pillow. More particularly, the present disclosure pertains to a pillow having a support structure to support head and the neck of a person while lying on a mattress.

BACKGROUND

Pillows are typically constructed with either soft fill material such as fiber, feathers or shredded foam materials encased within a fabric cover. Some pillows are molded from foam materials such as latex foam rubber or polyurethane foams. Typically pillows rest on the surface of the mattress, with the human head and neck placed on the pillow for support. The overall support of the pillow is compromised by the pillow following the compressive behavior of the mattress underneath. Soft and firm mattresses allow the pillow to compress into their surface to varying degrees.

DETAILED DESCRIPTION

Exemplary embodiments are described below with reference to the accompanying drawings. Unless otherwise expressly stated in the drawings, the sizes, positions, etc., of components, features, elements, etc., as well as any distances therebetween, are not necessarily to scale, and may be disproportionate and/or exaggerated for clarity.

The terminology used herein is for the purpose of describing example embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should be recognized that the terms “comprise,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. Unless otherwise specified, a range of values, when recited, includes both the upper and lower limits of the range, as well as any sub-ranges therebetween. Unless indicated otherwise, terms such as “first,” “second,” etc., are only used to distinguish one element from another. For example, one element could be termed a “first element” and similarly, another element could be termed a “second element,” or vice versa. The section headings used herein are for organizational purposes only and are not to be construed as limiting the subject matter described.

Unless indicated otherwise, the terms “about,” “thereabout,” “substantially,” etc., mean that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but may be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art.

Spatially relative terms, such as “right,” left,” “below,” “beneath,” “lower,” “above,” and “upper,” and the like, may be used herein for ease of description to describe one element's or feature's relationship to another element or feature, as illustrated in the drawings. It should be recognized that the spatially relative terms are intended to encompass different orientations in addition to the orientation depicted in the figures. For example, if an object in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the term “below” can, for example, encompass both an orientation of above and below. An object may be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein may be interpreted accordingly.

Unless clearly indicated otherwise, all connections and all operative connections may be direct or indirect. Similarly, unless clearly indicated otherwise, all connections and all operative connections may be rigid or non-rigid.

Like numbers refer to like elements throughout. Thus, the same or similar numbers may be described with reference to other drawings even if they are neither mentioned nor described in the corresponding drawing. Also, even elements that are not denoted by reference numbers may be described with reference to other drawings.

Many different forms and embodiments are possible without deviating from the spirit and teachings of this disclosure and so this disclosure should not be construed as limited to the example embodiments set forth herein. Rather, these example embodiments are provided so that this disclosure will be thorough and complete, and will convey the scope of the disclosure to those skilled in the art.

Reference in this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. The appearance of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Reference will now be made in detail to specific embodiments or features, examples of which are illustrated in the accompanying drawings. Generally, corresponding reference numbers will be used throughout the drawings to refer to the same or corresponding parts. Also, wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or the like parts.

Referring to FIG. 1 , a side sectional view of a pillow 100 is shown, according to example embodiments of the disclosure. The pillow 100 includes a first layer 104 that is a compressible layer and is adapted to compress under loading, and a support structure 106 engaged to the first layer 104 and supporting at least a portion of the first layer 104. The first layer 104 includes a first surface 108 (i.e., upper surface 108) and a second surface 110 (i.e., lower surface 110) adapted to be arranged proximate to a surface of a mattress or a bed, when the pillow 100 is positioned on the mattress or the bed. In the embodiment shown in FIG. 1 , the lower surface 110 may contact the mattress or a surface on which the person lies. Further, the upper surface 108 is arranged distally to the support structure 106, while the lower surface 110 is arranged proximal to the support structure 106. In an embodiment, the first layer 104 may be made of compressible material, such as, but not limited to, latex foam, down, feather, poly-fills, rubber, polyurethane foam, viscose, memory foam, polyester fibers, or any other foam, solid or shredded (also referred to as fillers), known in the art and is adapted to compress when a head/neck of a user is positioned over the pillow 100.

The support structure 106 is adapted to provide a resistance to the compression of the first layer 104 when the head and the neck is positioned on the pillow 100, thereby the support structure 106 prevents an undesired compression of the underlying mattress. As shown in FIG. 1 , the support structure 106 is embedded inside the first layer 104 and is adapted to be arranged proximate to the surface of the mattress and the lower surface 110 of the pillow. The support structure 106 is arranged/embedded inside the first layer 104 such that a thickness of a first portion 116 of the first layer 104 that extends from the support structure 106 to the upper surface 108 of the first layer 104 is greater than a thickness of a second portion 118 of the first layer 104 that extends from the support structure 106 to the lower surface 110 of the first layer 104. Additionally, or optionally, the pillow 100 may include a cover (not shown in FIG. 1 ) that surrounds and encloses the first layer 104. In some embodiments, the support structure 106 may be a flat plate (as shown in FIG. 1 ).

Referring to FIG. 2 , a pillow 200 according to an alternative embodiment is shown. The pillow 200 is similar to the pillow 100 except that a support structure 206 of the pillow 200 includes a curved plate 220 and a flat plate 222 whereas the support structure 106 includes only the flat plate. The curved plate 220 may be arranged at a location that supports or is arranged proximate to the head of the user when the person lies on the pillow 200.

Referring to FIG. 3 , a pillow 300 according to an alternative embodiment is shown. The pillow 300 is similar to the pillow 100 except that the support structure 106 is arranged underneath the first layer 104 and is engaged/attached to the first layer 104. Accordingly, the lower surface 110 of the first layer 104 is attached to the support structure 106. The support structure 106 may be adhesively attached to the lower surface 110 of the first layer 104. However, the support structure 106 may be coupled/engaged to the first layer 104 by any method or technique known in the art. Further, as with the pillow 100, the pillow 300 may include a cover (not shown) arranged surrounding and enclosing the first layer 104 and the support structure 106 such that a portion of the cover is arranged above and covering the upper surface 108 of first layer 104 and a portion of the cover is arranged underneath the support structure 106, covering the support structure 106 from below.

Referring to FIG. 4 , a pillow 400 according to another embodiment is shown. The pillow 400 is similar to the pillow 300 except that the pillow 400 includes a cover 402 and the support structure 106 is attached to the cover 402 and is arranged underneath the first layer 104. In an embodiment, the support structure 106 is engaged with the cover 402 by arranging the support structure 106 inside a cavity of the cover 402. Accordingly, the support structure 106 and the cover 402 together define a cover assembly 404 of the pillow 400 for covering and enclosing the first layer 104. In some embodiments, the support structure 106 is attached to an inner surface of the cover 402. In an embodiment, the support structure 106 may be adhesively attached to the inner surface of the cover 402. However, the support structure 106 may be coupled/engaged to the cover 402 by any method or technique known in the art.

Referring to FIGS. 5 and 6 , the support structure 106 according to an embodiment is shown. As shown, the support structure 106 defines an aperture 500 arranged substantially centrally to the support structure 106 corresponding to a position of the head of the user on the pillow 100, 200, 300, 400. The aperture 500 may include a substantially oval shape and extends from a top surface 114 of the support structure 106 to a bottom surface of the support structure 106. The aperture 500 facilitates in additional compression of a portion of the first layer 104 arranged directly above the aperture 500 and below the head of the user when the user lies on the mattress with the head arranged on the pillow 100 to provide a proper positioning of the head and alignment of the head and the neck. In the illustrated embodiment, the support structure 106 is made of non-compressible material, such as, but not limited to, board, plastic, plywood, composite material, metal, etc.

Additionally, or optionally, a first edge 502 of the support structure 106 may define a notch portion 504 corresponding to neck area such that notch portion 504 is arranged directly below the neck of the user and adjacent to shoulders when the person lies on the pillow 100. The notch portion 504 provides extra compression of the first layer 104, enabling proper alignment of the neck with the head. In an embodiment, the notch portion 504 includes a substantially concave shape and is arranged substantially centrally to the first edge 502. Although the support structure 106 having the aperture 500 and the notch portion 504 are shown and contemplated, it may be appreciated that the aperture 500 and/or the notch portion 504 may be omitted. In some embodiment, an elastic layer 510 (shown in FIG. 6 ) is attached to the top surface 114 of the support structure 106, and is arranged covering the aperture 500. In an embodiment, the support structure 106 is arranged inside an elastic sleeve, for example, a lycra-spandex sleeve, and the sleeve is laminated to the lower surface 110 of the first layer 104. Accordingly, the entire top surface 114 may be covered with an elastic layer 510. It may be envisioned that the support structure 106 may include structural features similar to the support structure 206 and in such a case, the cavity and the notch portion 504 are defined by the flat portion of the support structure 206.

Referring to FIG. 7 , a support structure 700 according to an alternative embodiment is shown. As shown, the support structure 700 includes a pair of posts, for example, a first post 702 and a second post 704, arranged/disposed spaced apart and may be substantially parallel to each other, and at least one rod 706 extending between the pair of posts 702, 704. In an embodiment, the posts 702, 704 are made of non-compressible material, such as, but not limited to, board, plastic, plywood, composite material, metal, etc. However, it may be appreciated that the posts 702, 704 may flex under loading. In some embodiments, the posts 702, 704 may be straight posts (as shown in FIG. 1 ). Alternatively, the posts 702, 704 may include a curved plate that may corresponds to the curved plate 220 of the support structure 206. The first post 702 and the second post 704 are identical in structure and construction, and for the sake of clarity and brevity, the structure and construction of only one post, for example, the first post 702, is explained in detail.

As shown in FIG. 8 , the first post 702 includes a first end 712, a second end 714 arranged opposite to the first end 712, and a plurality of holes 718 arrayed linearly between the first end 712 and the second end 714 and arranged spaced apart from each other. As shown, the plurality of holes 718 extends from an inner face 720 of the first post 702 towards an outer face 722 of the first post 702. It may be appreciated that distances between adjacently/consecutively disposed/arranged holes 718 may be kept constant or may be varied along the length of the first post 702 to vary the distances between the adjacently arranged rods 706.

In an embodiment, the plurality of holes 718 may include at least one blind hole and/or at least one through holes. For example, as shown in FIG. 8 , the plurality of holes 718 includes a plurality of first blind holes 724 arranged proximate to the first end 712 of the first post 702, a plurality of second blind holes 726 arranged proximate to the second end 714 of the first post 702, and a plurality of through holes 728 arranged/disposed/defined at a central portion of the first post 702. Accordingly, the through holes 728 are arranged between the first blind holes 724 and the second blind holes 726. Although two sets of blind holes 724, 726 are shown and contemplated, it may be appreciated that the first post 702 may define/include only one set of blind holes. In some embodiments, the plurality of holes 718 includes only through holes. Alternatively, the plurality of holes 718 may include only blind holes.

Referring back to FIG. 7 , the at least one rod 706 includes a plurality of rods 706 and the rods 706 are engaged/coupled to the posts 702, 704 by inserting/extending the rods 706 inside the associated aligned/facing holes 718 of the posts 702, 704. The plurality of rods 706 may include at least one rigid rod and/or at least one elastic rod, also referred to as at least one cord. It may be appreciated that the rigidity and elasticity are relative terminologies and are used herein to describe the relative rigidity or elasticity of one rod relative to another rod. Accordingly, the at least one rigid rod is less elastic or more rigid than the at least one cord.

As shown, the plurality of rods 706 includes at least one rigid rod, for example, a first rigid rod 730 and a second rigid rod 732, arranged proximate to the first ends 712 of the posts 702, 704, and a third rigid rod 734 and a fourth rigid rod 736 arranged proximate to the second end 714 of the posts 702, 704. The rigid rods 730, 732, 734, 736 extend in a lateral direction of the pillow 100 and may be arranged substantially perpendicularly to the posts 702, 704. As shown, the first and second rigid rods 730, 732 extend inside the first blind holes 724 of the posts 702, 704, while the third and fourth rigid rods 734, 736 extend inside the second blind holes 726 of the posts 702, 704. In an embodiment, the rigid rods 730, 732, 734, 736 are made of carbon fiber. However, it may be appreciated that the rigid rods 730, 732, 734, 736 may be made of any other suitable material, such as, but not limited to, wood, metal, or other suitable material having sufficiently rigidness.

Although two rigid rods are shown and contemplated to be arranged at each end of the posts 702, 704, it may be appreciated that only one rigid rod may be disposed at the first ends of the post and only one rigid rod may be arranged at the second ends of the posts 702, 704. Further, the rigid rods 730, 732, 734, 736 are connected to the posts 702, 704 such that when the cords are connected to the posts, the rigid rods 730, 732, 734 736 are prestressed, bowing the rigid rods 730, 732, 734, 736 into a concave shape initially. Accordingly, when the person lies on the pillow, the rigid rods 730, 732, 734, 736 become straight due to the pressure applied from above. In an embodiment, the rigids rods are flat plates having rectangular or square cross-section. The flat rigid rods 730, 732, 734, 736 have provide larger surface area, reducing the feeling of pressure at the surface of the pillow above the rods to the person lying on the pillow. Also, such rigid rods resist flexing or “splaying” when under tension and stress. The flat rigid rods operate like a leaf spring with most of the flexing limited to bowing in upward direction and downward direction. Further, the rigid rods 730, 732, 734, 736 act in unison with the posts 702, 704 to keep the elastic cords under tension. However, it may be appreciated that the rigids rods may be round or oval.

Further, the plurality of rods 706 includes at least one outer cord and at least one inner cord. The at least one outer cord, for example, a first outer cord 740 and a second outer cord 742, is arranged proximate to the at least one rigid rod. For example, the first outer cord 740 is arranged at a location adjacent to the second rigid rod 732, while the second outer cord 742 is disposed at a location adjacent to the fourth rigid rod 736. As shown, the first outer cord 740 is arranged in two rows or segments by extending the first outer cord 740 through the two consecutively arranged through holes 728 that are arranged proximate/adjacent to the first blind holes 724. Similarly, the second outer cord 742 is arranged in two rows or segments by extending the second outer cord 742 through the two consecutively arranged through holes 728 that are arranged proximate/adjacent to the second blind holes 726. Further, the at least one inner cord 744 is arranged between the two outer cords 740, 742. As shown, a single inner cord 744 extends through the plurality of aligned through holes 728 of the posts 702, 704 and therefore defines multiple rows or segments of the inner cord 744 arranged substantially parallel to the rigid rods 730, 732, 734, 736. Accordingly, the single inner cord 744 spirals around and between the posts 702, 704 into multiple parallel arranged segments/rows. It may be appreciated that the tension and/or elasticity of the inner cord 744 and the outer cords 740, 742 may be different from each other. Alternatively, the tension and/or the elasticity of the inner and outer cords 740, 742, 744 is identical. In some embodiments, the tension in the outer cords 740, 742 is kept relatively lower than the tension in the inner cord 744. Elasticity and/or tension in the cords 740, 742, 744 may be varied along the length of the posts 702, 704 (i.e., in the lateral direction of pillow 100) to achieve desired flexibility, compressibility, and/or rigidity at various location of the pillow 100. Also, the holes 718 and hence the rows/segments of the rods 706 may be arranged equidistant from each other. Alternatively, the distance between adjacent segments or rows of rods 706 may vary along the length of the posts 702, 704. For example, the distance between adjacent rows or segments of rods 706 may be decreased to reduce the compressibility at certain location relative to other location. In this manner, by controlling the tension, the elasticity, the density of rods 706, the flexibility, the compressibility, and/or the rigidity along the lateral direction of the pillow 100 may be controlled. In some embodiments, each of the first post 702 and the second post 704 may be arranged at an inclination relative to the lower surface 110 of the first layer 104.

Referring to FIG. 9 , a support structure 900 according to yet another embodiment is shown. The support structure 900 includes a hollow frame 902 having a pair of lateral members, for example, a first lateral member 904 and a second lateral member 906 disposed spaced apart and substantially parallel to each other, and a pair of longitudinal members, for example, a first longitudinal member 908 and a second longitudinal member 910, arranged spaced apart and substantially perpendicular to the lateral members 904, 906. The support structure 900 also includes a pair of posts, for example, a first post 912 and a second post 914, coupled to the lateral members 904, 906 of the frame 902, and at least one rod 916, extending in between the first post 912 and the second post 914. In the illustrated embodiment, the at least one rod 916 includes a single rod that is a flexible cord. However, it may be appreciated that at least one rod 916 may include multiple rods having at least one rigid rod and/or at least one flexible cords.

The pair of posts 912, 914 may be removably coupled to the lateral members 904, 906 of the frame 902. In the illustrated embodiment, thin carbon fiber pultruded bars are used as the posts 912, 914, however, any suitable non-compressible lightweight material, such as, but not limited to, board, plastic, plywood, composite material, metal, etc. may also be used. The first post 912 and the second post 914 are identical in structure and construction, and for the sake of clarity and brevity, the structure and construction of only one post, for example, the first post 912, is explained in detail.

As shown in FIGS. 10A and 10B, the first post 912 includes an upper surface 920, a lower surface 922, a first side surface 924, a second side surface 926, a first end 928, and a second end 930 arranged opposite to the first end 928. Further, the first post 912 includes an elongated groove 932 extending along a length of the first post 912 and is configured to receive a portion of first lateral member 904 of the frame 902. As shown, the elongated groove 932 extends from the first side surface 924 towards the second side surface 926 and including an opening defined at the second side surface 926. A portion of the first lateral member 904 is inserted inside the elongated groove 932 through the opening to engage the first post 912 with the first lateral member 904. Similarly, the second post 914 is engaged with the second lateral member 906 of the frame 902.

Moreover, the first post 912 defines a plurality of slots 938 arrayed linearly between the first end 928 and the second end 930. As shown, the plurality of slots 938 extends from the upper surface 920 of the first post 912 towards the lower surface 922 of the first post 912, and is configured to receive the at least one rod 916. Additionally, the first post 912 includes a plurality of hooks 940 arranged proximate to the second side surface 926 and arrayed in a lateral direction of the pillow 100 between the first end 928 and the second end 930. The hooks 940 are arranged spaced apart from each other and are disposed such that a single hook is disposed between two consecutively/adjacently disposed slots. Accordingly, a single slot is located between two adjacently/consecutively arranged hooks. It may be appreciated that each hook has an opening 950 at lower end and secure the at least one rod 916 with the posts 912, 914.

In an engagement of the rod 916 with the posts 912, the rod 916 is arranged in a plurality of parallel segments with each segment extending parallel to the longitudinal members 908, 910 and between aligned slots 938 of the two posts 912, 914. Further, a portion of the rod 916 that is located between two adjacent slots of the first post 912 extends in the lateral direction and is secured inside the hook 940 is arranged between the two slots. Similarly, a portion of the rod 916 is secured inside the hook 940 of the second post 914. Accordingly, as shown in the FIG. 10 , a first segment of the rod 916 extends from a first slot 938 a of the first post 912 to an aligned slot of the second post 914, then the rod 916 extends through the hook 940 of the second post 914 to an adjacent slot of the second post 914. Thereafter, a second segment of the rod 916 extends in the longitudinal direction from the adjacent slot of the second post 914 to an aligned slot 938 b of the first post 912. From the second slot 938 b of the first post 912, a portion of the rod 916 extends through an adjacently arranged hook to third slot 938 c of the first post 912. In this manner, the rod 916 spirals along the length of the frame 902 or the posts 912, 914 and is coupled/engaged with the posts 912, 914 and the frame 902. Although a single rod 916 is shown to be engaged in a spiral manner, it may be appreciated that the support structure 900 may include two or more rods of varying elasticity to provide varying compression along the pillow 100, 200, 300, 400.

In some embodiments, multiple rods of different tension and/or elasticity may be used in place of a single rod 916 to achieve desired flexibility, compressibility, and/or rigidity at various location of the pillow 100, 200, 300, 400. Also, the slots 938 and hence the rows/segments of the rod 916 may be arranged equidistant from each other. Alternatively, the distance between adjacent segments or rows of rod 916 may vary along the length of the posts 912, 914. For example, the distance between adjacent rows or segments of rod 916 may be decreased to reduce the compressibility at certain location relative to other location. In this manner, by controlling the tension, the elasticity, the density of rod 916, the flexibility, the compressibility, and/or the rigidity along the lateral direction of the pillow 100, 200, 300, 400 may be controlled. In some embodiments, each of the first post 912 and the second post 914 may be arranged at an inclination relative to the hollow frame 902.

The advantages of the pillow 100, 200, 300, 400 is now explained. The support structure 106, 206, 700, 900 of the pillow 100, 200, 300, and 400 defines rigid or semi-rigid portions of the pillow 100, 200, 300, 400 that supports the pillow 100, 200, 300, 400 on the mattress and creates a bridge-like effect where the pillow 100, 200, 300, 400 supports the head and neck in an uplifting manner relative to the mattress regardless of the sleeping position of the user. In addition, the support structure 106, 206, 700, 900 of the pillow 100, 200, 300, 400 prevents the compression of the first layer 104 beyond a certain limit. Moreover, the support structure 106, 206, 700, 900 of the pillow 100, 200, 300, and 400 prevents upward folding/rolling of lateral edges of the first layer 104 towards middle of the pillow 100, 200, 300, and 400, when the user lies on the pillow 100, 200, 300, and 400 as the support structure 106, 206, 700, 900 facilitates uniform distribution of weight of the user's head and neck on the pillow, thereby decreasing neck tension and improving breathing.
